3GPP2
The Third Generation Partnership Project 2 (3GPP2) is the
Partnership Project for Global cdma2000® Specifications
including:
• cdma2000 air interface specifications
• Mobile Application Part (MAP) core network specifications
• Wireless IP network specifications
• All IP multimedia domain specifications
• RAN specifications
• Other ancillary specifications
3GPP2 is also reviewing 3G and beyond work such as that for IMT-
Advanced
3
More Specifically, 3GPP2 is:
• A collaborative third generation (3G) telecommunications
specifications-setting project
• Comprised of interests from the Americas and Asia developing
global specifications for MAP “Wireless Radiotelecommunication
Intersystem Operations” network evolution to 3G
• Focused on global specifications for the radio transmission
technologies (RTTs) supported by MAP and the wireless IP core
networks, together known as the cdma2000 family of standards
